Re: Live Guest Relocation usage ?

[Tore Agblad]

Hi, we use it for some guests that during z/VM maint/reipl needs to be up.
Since most of our uptime critical guests is duplicated in two z systems with 
loadbalanser in front, 
it's just a few that needs relocate.
We do these manually, works fine.

Subject: Live Guest Relocation usage ?

Hi All -

We were having a discussion in the test lab here on the customer usage of
guest relocation on VM with SSI - so I decided to hit up the experts.

If you are able to, do you actually use the RELOCATE function ?
If so, how often ? How many at once ?
Do you drive it manually or have you written tools to do it for you ?


My theory was that we can guess a customer that performs RELOCATEs will do
so something like the following:

4 service outtages per year for CP service
times 2 LPARs ( at least )
times 2 relocates per guest ( Out, and back In )
times the number of guests that actually get relocated
== the number of relocates per year for that customer.


But I could be way off base - feel free to reply direct to me or to the
list - whatever suits your fancy.

Thanks!

Re: Live Guest Relocation usage ?

[Mauro Souza]

We are doing RELOCATE on our shop for at least two years now. Aside from a
strange issue with one LPAR (VMRELO MOVE took down the entire LPAR, IBM
could not pinpoint the error and the workaround didn't worked), we had no
more problems.

Every time we apply a PTF, all guests gets moved from one partition to the
other and back. A few times we had to create partitions on one mainframe,
we moved everyone to another mainframe, performed the PoR and sent everyone
home again. We moved guests to the DR site and back, no issues. Our guests'
uptime is larger than the zVM uptime.

We almost always move every guest from one partition to the other, rarely
we move just a couple of them. We usually create a script to do the move,
so it's almost automated.
